10Gb/s downstream and 6Gb/s upstream over 40km SSMFs are feasible for double-sideband AMOOFDM signals in wavelength-reused bidirectional-transmission colorless-WDM-PONs incorporating SOA/RSOA intensity modulators in OLTs/ONUs. Such performances are improved to 23Gb/s downstream and 8Gb/s upstream when single-sideband subcarrier-modulation is utilized.
We report the first long-haul DWDM transmission using three chirp-managed lasers spaced 50-GHz apart in SSMF at 10-Gb/s. Transmission penalties less than 0.7 dB over a dispersion-managed 1980-km link was measured with performance comparable to NRZ-OOK.
